MILWAUKEE (CBS 58) -- Protesters came from all across the area to gather outside Panther Arena Tuesday night, taking issue with everything from Trump's foreign policy to his immigration policy.

The group included members of nearly a dozen organizations, including Voces de la Frontera and Coalition to March on the DNC.

"I think it's important for us to make a stand that says we're not angry, but we're concerned with what's going on in our government, and having the President here is the perfect venue to do it," said protester Charlie Kenen.

Some say their issues are with the president's policies.

"We all need clean air and clean water," said Kate Fontanazza. "The Trump administration is allowing the rollbacks of the EPA."
